Construct the rigid body dynamics without external forces.

The rigid body dynamics from classical mechanics, or “Euler’s rotation equations”, describe the rotation of a rigid body in three-dimensional, principal, orthogonal coordinates.

A common citation for the rigid-body problem is p. 244 in the book by Hairer et al. (1993):
